Annual to tree, glandular or not. Leaf: simple to palmately or pinnately compound, generally alternate; stipules free to fused (0), persistent to deciduous. Inflorescence: cyme, raceme, panicle, cluster, or flowers 1; bractlets on pedicel ("pedicel bractlets") generally 0–3(many), subtended by bract or generally not. Flower: generally bisexual, radial; hypanthium free or fused to ovary, saucer- to funnel-shaped, subtending bractlets ("hypanthium bractlets") 0–5, alternate sepals; sepals generally 5; petals generally 5, free; stamens (0,1)5–many, anther pollen sacs generally 2; pistils (0)1–many, simple or compound, ovary superior to inferior, styles 1–5. Fruit: 1–many per flower, achene (fleshy-coated or not), follicle, drupe, or pome with generally papery core, occasionally drupe-like with 1–5 stones. Seed: generally 1–5 (per fruit, not per flower).
110 genera, ± 3000 species: worldwide, especially temperate; many cultivated for ornamental, fruit, especially Cotoneaster, Fragaria, Malus, Prunus, Pyracantha, Rosa, Rubus. [Potter et al. 2007 Plant Syst Evol 266:5–43] Number of teeth is per leaf or leaflet, not per side of leaf or leaflet, except in Drymocallis. —Scientific Editors: Daniel Potter, Thomas J. Rosatti.

Shrub, small tree, evergreen. Stem: trunk < 80 cm diam; bark generally gray to red-brown; twigs short. Leaf: generally clustered, simple; stipules deltate to lanceolate, generally deciduous; blade ± thin to leathery, entire to toothed. Inflorescence: clusters, flowers 1–18. Flower: hypanthium funnel-like, tube persistent in fruit, rim cup-like, deciduous, bractlets 0; petals 0; stamens 10–46, in ± 3 rows on hypanthium rim, anthers glabrous or hairy; pistil 1, free from hypanthium tube, ovary superior, 1-ovuled, style terminal, persistent in fruit, straight or twisted in age, plumose. Fruit: achene, cylindric, hairy, included in hypanthium tube.Key to Cercocarpus
